How to change your password on Linux – safely
Knowing how to change your password on Linux is one of the first things to do with a new machine, and it takes under a minute. This guide shows the simple way to change it, plus one vital warning about Linux passwords that every owner should understand before they start.
The easy way – through Settings
Open Settings → Users, select your account, and click Password. Enter your current password once, then your new password twice, and confirm. That’s it — the change takes effect immediately, and you’ll use the new password the next time you log in or unlock the screen.
The terminal way
You can also change your password on Linux from a terminal with a single command:
passwd
It asks for your current password, then the new one twice. Nothing appears as you type — that’s normal, Linux hides password characters for security. Press Enter after each.
Choose a strong but memorable password
Aim for something long rather than complicated — a passphrase of a few unrelated words is both stronger and easier to remember than a short string of symbols. Avoid reusing a password from another account, and if you juggle many logins, a password manager is well worth setting up.
The one warning that really matters
On Linux, your password genuinely protects your data — which means if you forget it, it cannot simply be reset or recovered. There is no back door. Unlike some systems, a lost Linux password generally means the machine has to be wiped and set up again to regain access, losing anything not backed up. Write your new password down and keep it somewhere safe, or store it in a password manager.
Back up before you rely on memory
Because a forgotten password can mean a full reinstall, keep a current backup of your files (see our guide to backing up your home folder). That way your documents and photos are safe no matter what.
